Key Points Aitken-mode particles contributed significantly to cloud droplet formation in the high Arctic, especially after the transition to fall Uploaded on Nov 09, 2014. Properties of Hydrogen Bonding Cohesion-Allows individual water molecules to stick to each other (cluster), giving water a high surface tension. The five main properties of water are its high polarity, high specific heat, high heat of vaporization, low density . (think of the water on the penny or paper clip on waterthis is due to cohesion and surface tension). It includes atmospheric water vapor, rainwater, river water, groundwater, lake water, polar icecaps, sea and the ocean waters. For the most basic understanding, seawater is simply a solution of water (H2O) and salt. This high energy state causes the molecules to be always moving reducing the likelihood of bonds between individual molecules from forming. Salinity and Chemical Properties. However, when we collect small samples of ocean water break down the chemical formula into its elemental properties, we can see that seawater is as follows: Oxygen - 86%. The turbidity is measured by a turbidity rod or by a turbidity meter with optical observations and is expressed as the amount of suspended matter in mg/l or parts per million (ppm).
